[mininet-discuss] nox_core_dir missing env

Dear Zoltan!


After installation of NOX Classic, I have a directory named "noxcore" inside the "/home/mininet" directory. But it does not contain any file named "nox_core"! So where to find the NOX executable file?



Thanks...

Hi,
 
As in the walkthrough: “NOX_CORE_DIR env var must be set to the directory containing the NOX executable”.
Execute first something like:
 
export NOX_CORE_DIR=/this/is/where/my/nox_core/is
 
Regards,
Zoltan

Hi! 



I am posting on this forum for the first time. I am using mininet 2.1.0 on VMware Workstation 10. I have installed NOX Classic by following the instructions on "Mininet Walkthrough". But after its installation, the command
"$ ./nox_core -v -i ptcp:" generates the following error:





-bash: ./nox_core: No such file or directory





And then the command "$ sudo -E mn --controller=nox,pyswitch --test pingpair" generates the following error:





*** Creating network

*** Adding controller

exiting; please set missing NOX_CORE_DIR env var





I have also deleted the line "#Defaults env_reset" from "sudoers" file in "etc" directory but no success. Then I also wrote "#Defaults root" instead of "#Defaults env_reset" in the same file but still no success.






Please reply comprehensively.





Thanks!
